VENU-833 1 night and 2 days Rena Fukiishi was left behind by her wife's older sister who suddenly came to her

Kenta was really in trouble. The cause of this was the strange behavior of her sister-in-law, Rena. It's okay as far as the fact that he came to help with the housework while his wife was home due to pregnancy. However, there were too many strange actions after that. She came into the bathroom naked to wash her back... (Are you really asking me out?...No, it's not like that.) I'm making fun of Rena's mysterious behavior.
